Tire tread



FIG. 1 is a front perspective view of a tire tread showing my new design, it being understood that the tread pattern repeats uniformly throughout the circumference of the tire and that the opposite side perspective view is identical to that shown; and,

FIG. 2 is an enlarged fragmentary plan view of a portion of the tread of my new tread design as shown in FIG. 1.

The broken line showing of a tire inner bead and sidewall is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
